Hello,I have a standalone client that sends a message to a queue and publishes a message to a topic. The message is delivered almost immediately to the queue whereas it takes much longer to deliver the message to the topic.Why is that??Thanks in advance,Julien.

Pub/Sub LatencySince there is typically some latency in all pub/sub systems, the exactmessages seen by a subscriber may vary depending on how quickly a JMSprovider propagates the existence of a new subscriber and the length of time aprovider retains messages in transit.For instance, some messages from a distant publisher may be missed because itmay take a second for the existence of a new subscriber to be propagatedsystem-wide. When a new subscriber is created, it may receive messages sentearlier because a provider may still have them available.JMS does not define the exact semantics that apply during the interval when apub/sub provider is adjusting to a new client. JMS semantics only apply oncethe provider has reached a ?steady state? with respect to a new client.
